CVE-2023-5135

CVSS v3.1

Medium

VectorAV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Name of the Vulnerable Software and Affected Versions The Simple Cloudflare Turnstile plugin for WordPress versions up to, and including, 1.23.1
Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes in the gravity-simple-turnstile shortcode. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.
Recommendations For versions up to, and including, 1.23.1, update to a version that addresses the insufficient input sanitization and output escaping issue in the gravity-simple-turnstile shortcode. As a temporary workaround, consider restricting access to the gravity-simple-turnstile shortcode for users with contributor-level and above permissions until a patch is available.
